### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very good case, much like the smaller official case for IPhone 7
  

*by M***Y on Reviewed in the United Kingdom on 23 August 2017*

I have only just received this case, it is exactly what I was looking for. That is a power case similar to the official apple case I had on my smaller iPhone 7. The only real difference it has a button to charge your phone when it needs it. Very easy to slide your phone in or out of. Good quality rubber exterior, and not too bulky, still keeping a lightning port to charge you case and phone simultaneously and still charges perfectly in my dock. Spot on 👍👍👍

### ⭐ 1.0 out of 5 stars







  
  
    breaks easily
  

*by A***R on Reviewed in the United Kingdom on 29 July 2018*

Bought it in February to use over summer period as an emergency charger. Put it on 5 weeks ago before my holiday. Removed it today to clean the phone inside only to discover that plugging part broked and charger doesnt work anymore.I took it off slowly, not forced it or something. Shame as look is great and worked pretty well. Not recommend.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Stopped working after 4 weeks :(
  

*by T***N on Reviewed in the United Kingdom on 13 January 2018*

Was great until all of a sudden it stopped working! I'm hoping mine was just a misbuild or something as every one elses is working fine so that's why I'm giving it a 3 star instead of one, going to order another and see if it was just a badly made unit
